Hi Jason,
Wondering if you can help.
I am using the latest version of Ecart 5, my poroducts list is called "items" and the stock availability in items is called "available". The code is on the confirm page and the payment gateway is PayPal Standard.
I have followed the code above (including the small change you made) but I am get two problems.
Firstly when going to the confirm with a product in the cart I get the following error:
Notice: Undefined property: eCart1_ItemDefinition::$available in C:\vhosts\cuteascandy\WA_eCart\WA_eCart_Definition_PHP.php(119) : eval()'d code on line 1
Secondly the "available" column in the items table was set to 20 available, but after it goes to the confirm page it shows -1.
My code block is below.
Hope you can help.

while (!$eCart1->EOF()) {
$_GET['available'] = $eCart1->DisplayInfo("available"); ?>
$var1_getAvailable = "-1";
if (isset($_GET['available'])) {
$var1_getAvailable = $_GET['available'];
mysql_select_db($database_dbCute, $dbCute);
$query_getAvailable = sprintf("SELECT ItemID, available FROM items WHERE items.ItemID=%s", GetSQLValueString($var1_getAvailable, "int"));
$getAvailable = mysql_query($query_getAvailable, $dbCute) or die(mysql_error());
$row_getAvailable = mysql_fetch_assoc($getAvailable);
$totalRows_getAvailable = mysql_num_rows($getAvailable);?>
<?php $_GET['available'] = ($row_getAvailable['available'] - $eCart1->DisplayInfo("Quantity")); ?>
// WA DataAssist Update
if ($_SERVER["REQUEST_METHOD"] == "POST") // Trigger
$WA_connection = $dbCute;
$WA_table = "items";
$WA_redirectURL = "";
if (function_exists("rel2abs")) $WA_redirectURL = $WA_redirectURL?rel2abs($WA_redirectURL,dirname(__FILE__)):"";
$WA_keepQueryString = false;
$WA_indexField = "ItemID";
$WA_fieldNamesStr = "available";
$WA_fieldValuesStr = "".$_GET['available'] ."";
$WA_columnTypesStr = "none,none,NULL";
$WA_comparisonStr = "=";
$WA_fieldNames = explode("|", $WA_fieldNamesStr);
$WA_fieldValues = explode($WA_AB_Split, $WA_fieldValuesStr);
$WA_columns = explode("|", $WA_columnTypesStr);

$WA_where_fieldValuesStr = "".$eCart1->DisplayInfo("ID") ."";
$WA_where_columnTypesStr = "none,none,NULL";
$WA_where_comparisonStr = "=";
$WA_where_fieldNames = explode("|", $WA_indexField);
$WA_where_fieldValues = explode($WA_AB_Split, $WA_where_fieldValuesStr);
$WA_where_columns = explode("|", $WA_where_columnTypesStr);
$WA_where_comparisons = explode("|", $WA_where_comparisonStr);

$WA_connectionDB = $database_dbCute;
mysql_select_db($WA_connectionDB, $WA_connection);
$updateParamsObj = WA_AB_generateInsertParams($WA_fieldNames, $WA_columns, $WA_fieldValues, -1);
$WhereObj = WA_AB_generateWhereClause($WA_where_fieldNames, $WA_where_columns, $WA_where_fieldValues, $WA_where_comparisons );
$WA_Sql = "UPDATE `" . $WA_table . "` SET " . $updateParamsObj->WA_setValues . " WHERE " . $WhereObj->sqlWhereClause . "";
$MM_editCmd = mysql_query($WA_Sql, $WA_connection) or die(mysql_error());
if ($WA_redirectURL != "") {
if ($WA_keepQueryString && $WA_redirectURL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "" && sizeof($_POST) > 0) {
$WA_redirectURL .= ((strpos($WA_redirectURL, '?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
header("Location: ".$WA_redirectURL);
